ADJUSTABLE SHOE JACK.

Application filedJune 19,

This invention aims to provide novel means for holding a shoemakers last adjustably but firmly in such a position that the last may be turned with respect to a vertical axis, thereby presenting the work conveniently to the shoemaker.

It is within the province of the disclosure to improve generally and to enhance the utility of devices of that type to which the invention appertains.

With the above and other objects in view which will appear as the desm'iption proceeds, the invention resides in the combina tion and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, may be made within the scope of what is claimed, without departing from the spirit of the invention.

In the drawings t Figure 1 is an elevation; and

Figure 2 is a section wherein parts appear in elevation.

The numeral 1 marks a tubular bearing extended through a work bench 2 or the like, the bearing being supplied intermediate its ends with an outstanding flange 3 resting on the bench 2, and connected to the bench by securing elements 4, such as bolts, the securing elements passing through the bench and the flange. The numeral 5 marks a standard on which a last 6 is detachably mounted, in the usual way, as indicated at 7 in dotted line in Figure 1. The last 6 has a thinned edge 8. The edge 8 enabels shoemakers to shove the welt further under than is usually the case, and the shoemaker, therefore, can cement the soletightly in place before the sole is sewed on. The standard 5 includes a reduced body 9 of circular cross section mounted to rotate in the tubular bearing 1, the standard being supplied intermediateits ends with an abutment 10 which engages the upper end of the bearing 1 and limits the downward movement of the stand ard 5 andthe last 6 under the action of a compression spring 11 engaged about the 1926. Serial m5. 117,068.

lower threaded end 12 of the body 9, one end of the spring 11 engaging an adjusting device, such as a nut 14 threaded on the part 12, the upper end of the spring 11 being engaged with a washer 15 which is pressed against the lower end of the bearing 1. The

spring 11 is a strong spring, and its effort may be adjusted by means of the nut 14. The spring 11 prevents the standard 5 from turning around too readily in the bearing 1, and the last 6, therefore, will stand properly positioned with respect to the shoemaker whilst the work is being done. The shoemaker, however, can forcibly rotate the standard 5, and position the last 6 in any. convenient relation with respect to himself.

What is claimed is i In a device of the class described, a tubular bearing provided intermediate its ends with an outstanding attaching flange which constitutes a bench-engaging support for the bearing, the bearing being of a common diameter below the flange, whereby the lower part of the bearing can be pushed downwardly in a hole in a bench which receives the bearing closely, thereby to. bring the flange into engagement with the upper surface of the bench, a cylindrical standard a portion of which is journaled for rotation in the bearing, the length of the said journaled portion being more than twice its diameter, to insure stability and to provide anjadequate wearing surface, the standard being provided with an abutment engaging the upper end 'of the bearing, the lower end of the standard being exposed throughout its entire periphery below the extreme lower end of the bearing, a nut threaded on the lower end of the standard, a compression spring disposed about the lowerend of the standard, one end of the spring engaging the nut, and the other end of the spring exerting a thrust agaiirt the extreme lower end of the bearing, and a. last mounted on the upper end of the standard.

In testimony that I claim the foregoing as my own, I have hereto affixed my signature.
